Do you still get free plastic bags from the supermarkets? Things have changed.

China has banned（禁止）free plastic bags at shops and supermarkets，and people have to pay for using plastic bags. The rule started on June 1,2008. It came because our country tried to make litter less. Making super-thin（超薄）plastic bags has also been banned.

The Chinese once used about 3,000,000,000 plastic shopping bags a day，and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.

What kind of shopping bag is the best to bring? Some students in Chongqing have a good idea. They make their own shopping bags. They use old clothes to make cloth bags（布袋），and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty（责任）to protect the environment.

The size and shape（外形）of your ears show your character（性格）more than any other part of the face. Other parts of the face change shapes as we get older，but ears do not change their shapes. They only change in size.

Reading people’s character from their ears is a very old science. In the past people thought that a person’s ears with colour was dangerous. They also thought that the shape of the ears showed if a person was musical or not. Today，too，many people believe that the size and shape of the ears help you know if a person is musical.

Ears are all different，and each different thing has a meaning. Next time you look at a person，see if his or her ears are large，medium-size，or small. Look at the lobes（耳垂）.Do they stick to the face? Ears that are always red mean that a person may get angry easily. Ears that are always cold and nearly white colour mean that a person has a nervous（神经质）character.

( )1. Reading people’s character from their ears is .

A.only for music B．an old idea

C．very new D．a good way to talk with others

( )2. When one’s ears are red，it means .

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

Reduce

Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

Reuse

Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup of a paper bag. It’s better to use a china cup and a lunch box because you can use them again.

Recycle

Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programs. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

So please remember these three words: reduce, reuse and recycle.

( ) 1. What is the passage about?

A. How to produce things. B. How to burn things.

C. How to help others. D. How to be green.

( ) 2. Which of the following is right?

A. Don’t waste things. B. Always throw away old things.

C. Always buy new things. D. Buy too many things from abroad.

( ) 3. Why is it better to use a china cup and a lunch box?

A. You can burn them.

B. You can use them again.

C. You can throw them away.

D. You can change them into something else.

( ) 4. To protect the environment, we should remember these three words: _______.

Scientists have helped people understand the dangers facing the earth. As people live on the earth, we should be fully ready to deal with the dangers. If we do not pay more attention to the problems caused by air pollution, our earth may no longer be a healthy place for plants, animals, and people to live.

Cleaning up the air is a job that all countries must work on. The problems caused by air pollution can be solved, but a lot of work needs to be done. Governments around the world are beginning to work together to lower the levels of dangerous gases in the atmosphere(大气层). If this can be done well, the ozone layer(臭氧层) can rebuild itself, global warming can be controlled, and acid rain can be reduced.

In 1967, the government of the United States passed the Clean Air Act. More parts were added to the act in 1970, 1977 and 1990. As a result of these laws, cars now must reduce the amounts of harmful gases. Power factories must use "clean coal" methods to reduce acid-rain gases they produce.

In 1970, the Environmental Protection Agency (EPA) was set up. The EPA's job is to make sure that the environmental laws are being followed and to find out new dangers and offer solutions. The first Earth Day was also celebrated in 1970.

While it is very important to address with air on a global scale, each person can also do something to protect the Earth. Here are some things you can do every day:

1) Turn down the heat and air conditioning.

2) Use the dishwasher only when they are full of dishes.

3) Practice the 3 Rs: recycle, reuse, and reduce.

4) Plant a tree.

5) Walk or ride your bike.

( ) 1. If we don't care about _____ problems, our earth may no longer be a healthy place.

A. Air pollution B. Water pollution C. Noise pollution

( ) 2. Every country should _____ to solve the problems caused by air pollution.

A. rebuild the ozone layer B. clean up the air

C. produce harmful gases

( ) 3. All the things the EPA can do is to _______

A.make more laws B. find out new dangers

C. protect the environment

( ) 4. The Clean Air Act was passed ________ by the American government.

A. In 1967 B. In 1970 C. In 1977

( ) 5. In our daily life, we can do something to protect the earth by _______.

With the World Environment Day coming, our school is now requiring every student to form a habit of sorting(分类)the waste. Here in our schoolyard we lay four different colors of rubbish bins for different kinds of rubbish. The red is for harmful waste; the blue is for waste that can be recycled; the green is for kitchen waste; the yellow is for other waste.

The followings are some instructions for you.

Glass: Empty bottles without caps can be recycled to make new

glass bottles.

Warning: Mirrors and light bulbs(电灯泡) must not be included in the glass waste.

Paper: Newspapers, magazines, boxes must be clean enough to be recycled.

Warning: Paper tissues(餐纸) and wall paper are not recyclable as paper and should be kept separately.

PMD waste: Packaging made of Plastic or Metal and Drink boxes are used to make new packaging.

Warning: Plastic pots (e.g. yoghurt pots), plastic bags must not be included with the PMD waste.

Harmful waste: out-of-date drugs, used batteries, paint and oil…

The search for life outside the Earth may have moved to a new and exciting level. A team of astronomers ( 天文学家) said they have found a new planet that has many important parts similar to those of the Earth.

The planet, which travels around a red dwarf star( 红矮星) called Gliese 581, has the right size and temperature. Most importantly, the planet lies in the suitable living area of the star, which makes the planet not too hot or too cold.

Scientists say the new world, Gliese 581C is five times larger than the Earth. It may have water since it is in the right place for the red dwarf to survive in space.

Swiss scientist Michel Mayor said it is an important step on the way to find possible life in the space and there are still lots of questions.

For more than ten years, astronomers and scientists have been keeping their eyes on the space in search for another Earth, another world that can support life or already has it.

According to records, the first discovery of extra solar(太阳系) planet going around a normal star was made in 1995. Since then, the number of newly discovered worlds has increased to about 200. But they are just dead with lifeless bodies.

The Gliese 581C came into our eyes and mankind has reason to celebrate. After all, we may have living neighbours. The discovery doesn't promise much, but it offers hope that there could be other people or living things out there.

( )1. The new planet has made_________.

A. the search for life outside the Earth new and exciting

B. many important parts of the Earth new and similar

C. a red dwarf star not too hot or not too cold

D. the astronomers believe everything

( )2. The new planet goes around_________.

( ) 4. Why do astronomers and scientists keep their eyes on the space?

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil（土壤）-make the rain in-and also bind（粘合） the soil, thus（这样） stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

1. The most important points of trees to man is that________.

A. they help him to make money B. they give him cool

C. they give him wood and other things D. they help him to stop drought and floods

2. In many places forests slowly disappear because ________ .

A. many trees have been cut down by man

B. new trees are not well looked after

C. man has not paid enough attention to planting trees

D. all the above

3. Land becomes desert after all trees are cut down because ________ .

A. roots of trees break up the soil

B. there are too many rainfalls

C. strong winds bring a lot of sand

D. there are no longer trees to keep the rain and protect the top-soil.

Snake dishes have become popular in recent years. Snake meat is often seen in restaurants. It seems that eating snake is now in fashion, and if you haven’t eaten snake yet, you’re considered “out of date”.

But I wonder whether all of the trends（趋势）are worth following.

Some people may defend（辩解）themselves by saying that eating snake is good for their health. But these people don’t find out that mice and worms are often in snakes’ bodies, therefore, there are many parasites（寄生虫）found inside snakes. They may be bad for our health.

Apart from this, we’re sorry to see that more snakes are being killed by a butcher’s knife.

According to the English newspaper, “Shanghai Star, about 1000 tons of snake are eaten every year in China. In Shenzhen of Guangdong Province, sometimes as many as 10 tons of snake are served on dinner tables in a single day.

If we still turn a blind eye to this, a vicious circle（恶性循环）will be created:if more snakes are eaten by people, the number of snakes will drop, but the number of mice will increase, which will result in a decrease of crop output.

This will make more people hungry. Who wants to see such a tragedy happen?

Therefore, let's not to eat snake any more. To protect the snake is to protect ourselves.

Smog(雾霾) is a big problem in many Chinese cities. But it seems that besides wearing a mask, few of us know what has caused the smog and what to do to beat it. Chai Jing, a former news hostess with China Central Television, discussed the questions in her documentary Under the Dome.

The 103 - minute film was published on major Chinese video - sharing websites on Feb 28. In the film, Chai visits polluted places and talks to officials and scientists. She comes to the conclusion that burning too much coal and oil are the main causes of PM2.5 and smog.

To make things worse, according to Chai, the coal and oil we are burning is of poor quality and don't meet the standards for environmental protection. Therefore they have produced more harmful gas to pollute the air.

To solve the problem, Chai suggests that we should clean our coal and oil or replace them with cleaner energy such as natural gas. In her film, Chai also pointed out that ordinary people can do something to help control smog too. For example, we live a greener life by using more public traffic. Or if we see things that could harm the environment, we can try to stop it. In one scene from the fihn, Chai sees a dirt mound in a building site exposed in the air, and asks the person in charge to cover it. When she sees a restaurant cooking without any suitable filter facilities, she calls the hotline 12369. The restaurant installed the filter a week later.

Chen Jining, the new minister of environmental protection, praised Chai. "This film encourages ordinary people to care about the environment. This is what we need in the future. "

( ) 1.What do most of people do to deal with the smog?

A. Wear a mask. B. Think of ways to beat it.

C. Find out what has caused it. D. Take a documentary.

( ) 2.What is the main cause of smog according to Chai?

A. Setting off too many fireworks. B. Burning too much coal and oil.

C. Too many cars in big cities. D. Too many factories and companies.

( ) 3.Which of the following is NOT Chai's suggestions towards reducing smog?

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.

Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of(缺乏) others, for example, fresh water(淡水). It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps(水龙头) when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

1. From the passage we know that some students often _______in the school.

April 22 is Earth Day. Everyone on earth should care about and protect the earth!

The earth has warmed by about 1°F(华氏度) over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which make the earth warmer.

First, the greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.

People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.

1．Earth Day is probably created for people to________．

A．learn more about the earth

B．make full use of the earth

C．take better care of the earth

D．study the warmth of the earth

2．We can infer (推断) from the passage that the reasons for the warmer earth are____now.

The world develops more and more quickly, while it is also polluted more and more seriously. Luckily, there are many ways to deal with the negative effects on the environment. One of these is driving an electric car. Electric cars produce about 80 percent less pollution than gas-powered cars.

Besides, electric cars have more benefits than gas-powered cars for several reasons. First, the energy of electric cars is regenerative , which means that when you brake（刹车）in an electric car, you can charge（充电）the battery again. However, when you brake in a gas-powered car, you actually use energy. Also, during producing electric cars, engineers spend more time and energy making electric cars lighter so that there will be less drag(阻力) from the wind. This allows an electric car to travel farther using less energy than a gas-powered car.

Driving an electric car can not only save energy, but also save more money and time. For example, it costs less to repair (维修)such a car. The cost of charging an electric car is about 20 percent of the cost of gas, and electric cars require less repair than gas-powered cars. This is because electric cars have no cooling systems and the other moving parts. There are fewer possible problems without the moving parts. Electric cars can also save people’s time. Gas-powered cars need to be checked in a few months, while all that you need to do is only replacing the battery every four years for an electric car. Now some people have begun to drive electric cars in several big cities of China. Though it may take a little time to get used to it, due to the great advantages, more and more people will use electric cars in the future.

People often decide where to live based on the natural resources in the area. Natural resources are things that are useful to people and come from the earth. Materials for building houses are natural resources. So are foods, such as fruits, vegetables, animals that could be caught or hunted and water.

The weather and landforms let certain things grow in different areas. They also determine(决定) which living things will be able to grow there. Areas with very rich soil are made to be good farming communities. Poor soil may send farmers to look for better places. However, areas with poor soil may attract those who have other purposes for the land. Poor soil doesn’t matter if you want to build a factory. It also doesn’t matter if it grows grass well.

Each area attracts people based on their interests and purposes. Areas that support many different interests will naturally have larger populations. You may not think of the mountains, lakes or oceans as natural resources. In fact they are. Villages and cities built near water sources have been the most successful. People who want to catch fish for a living choose to live by the ocean, instead of the desert. People living near water can use it to meet their daily needs.

Places that are difficult to reach will naturally have fewer people. Places that are high on mountain tops are not very desirable to most people. Neither are places that are in the middle of hot, dry deserts.

For too long, humans have destroyed resources. We have been using up those that can’t be easily replaced. Renewable(可再生的) resources are those that can be replaced easily. We are lucky to have many resources that are renewable, such as the sun, wind, water and trees. We need to use more renewable resources. This will protect our planet.

( )4．From the sentences“More people more waste”，we know that ．

A．because of the increase of population and the development of industry，more and more waste is produced

Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no modern medicine, either.

Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.

Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt (被状物) over a city. This kind of quilt is called smog(烟雾).

Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, and they mustn’t let dirty smoke go into the air.

We need to do many other things. We can put waste things in the dustbin and do not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
